Microsoft Speech to Text Python SDK SPXERR_INVALID_HEADER问题

Question

[Microsoft Python Speech-to-Text Quickstart ("Quickstart: Recognize speech from an audio file")与azure-cognitiveservices-speech v1.8.0 SDK一起使用时出现以下错误。

RuntimeError: Exception with an error code: 0xa (SPXERR_INVALID_HEADER)

• 快速入门代码：https://docs.microsoft.com/en-us/azure/cognitive-services/speech-service/quickstarts/speech-to-text-from-file?tabs=linux&pivots=programming-language-python#sample-code
• SDK：https://pypi.org/project/azure-cognitiveservices-speech/

此文件只有3个输入：

• Azure订阅密钥
• 天蓝色服务区域
• 文件名

我正在使用以下测试MP3文件：

• https://github.com/grokify/go-transcribe/blob/master/examples/mongodb-is-web-scale/web-scale_b2F-DItXtZs.mp3

这是完整的输出：

Answer 1

mp3编码的音频不支持作为输入格式。请使用WAV（PCM）文件，该文件具有16位样本，16 kHz采样率和单个通道（单声道）。
